The invention relates to a method for preparing a benzene adsorbing material by utilizing a discarded activated aluminum oxide. In the method, an activated aluminum oxide/active carbon composite material which has a high adsorption effect on benzene is prepared by cleaning, filtering and drying the discarded activated aluminum oxide and by closed heat treatment at low temperature. In the method, due to the adoption of a closed low-temperature heat treatment mode, holes which are blocked in the discarded activated aluminum oxide can be perforated, and organic matters adsorbed to the discarded activated aluminum oxide can be directly discomposed and carbonized and stored in the aluminum oxide holes to form active carbon, so air pollution is reduced. The method has a novel process, is simple, easy and low in cost and has a high environment friendliness and economic value, and wastes can be turned into wealth.

A totally integrated ventilation system is contained in the outside air inlet stream. The system samples and controls ventilation airflow as it enters a structure. An air valve connecting the outside air inlet stream to the return plenum is controlled by a valve positioning device and a processor that monitors sensors located in the outside air inlet stream, air quality data provided by a telecommunications link and the HVAC system control signals. The air quality data includes locally broadcast air pollution data or air quality alert data related to accidents or terrorist attacks. The processor and valve positioning device simultaneously control a separate pressure relief valve that allows contaminated air to be exhausted from the structure.

A controller for directing operation of an air pollution control system performing a process to control emissions of a pollutant has multiple process parameters (MPPs). One or more of the MPPs is a controllable process parameter (CTPP) and one of the MPPs is an amount of the pollutant (AOP) emitted by the system. A defined AOP value (AOPV) represents an objective or limit on an actual value (AV) of the emitted AOP. The controller includes either a neural network process model or a non-neural network process model representing a relationship between each CTPP and the emitted AOP. A control processor has the logic to predict, based on the model, how changes to the current value of each CTPP will affect a future AV of emitted AOP, to select one of the changes in one CTPP based on the predicted affect of that change and on the AOPV, and to direct control of the one CTPP in accordance with the selected change for that CTPP.
